Clutch Switch Circuit

DESCRIPTION

Clutch switch circuit inspection is necessary for M/T vehicles.
When the clutch pedal is released, the ECM receives positive (+) battery voltage through the ECU IG fuse. While depressing the clutch pedal, the clutch switch sends a signal to terminal D of the ECM. The ECM cancels cruise control drive when terminal D receives the signal.

INSPECTION PROCEDURE

PROCEDURE

1. INSPECT ECM




(a) Disconnect the C24 connector from the ECM.
(b) Turn the ignition switch on (IG).
(c) Measure the voltage according to the value(s) in the table below.
Standard voltage:






OK -- PROCEED TO NEXT CIRCUIT INSPECTION SHOWN IN PROBLEM SYMPTOMS TABLE
NG -- Continue to next step.
2. INSPECT CLUTCH SWITCH




(a) Turn the ignition switch off.
(b) Disconnect the A21 connector from the clutch switch.
(c) Remove the clutch switch.
(d) Measure the resistance according to the value(s) in the table below.
Standard resistance:






NG -- REPLACE CLUTCH SWITCH
OK -- Continue to next step.
3. CHECK HARNESS AND CONNECTOR




(a) Measure the resistance according to the value(s) in the table below.
Standard resistance:






NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR (ECM - CLUTCH SWITCH)
OK -- REPAIR OR REPLACE HARNESS OR CONNECTOR (BATTERY - CLUTCH SWITCH)
